Smoothing Out Data Series

Written by Allen Wyatt (last updated October 14, 2023)
This tip applies to Excel 97, 2000, 2002, and 2003


When you are creating line charts in Excel, the lines drawn between data points tend to be very straight. (This makes sense; the lines are meant to connect the points.) You can give your graphs a more professional look by simply smoothing out the curves Excel uses at each data point. Follow these steps:

  1. In your chart, right-click on the data series that you want to smooth. Excel displays a Context menu.
  2. Choose Format Data Series from the Context menu. Excel displays the Format Data Series dialog box.
  3. Make sure the Patterns tab is displayed. (See Figure 1.)
  4. Figure 1. The Patterns tab of the Format Data Series dialog box.

  5. Select the Smoothed Line check box. (If the check box is not visible, it means you are not working with a line chart. Only lines in a line chart can be smoothed.)
  6. Click on OK.
